| Abstract: | Due to the TSK fuzzy model is multi -constraint and multi -target optimization which is difficult to learn, GA - BP hybrid learning method for the model was proposed. Some problems related to a species coding means for the model structure, evolution and fitness evaluation strategy were discussed. The error back propaga- tion algorithm （BP） for training the antecedent and consequent parameters during the process of evolution was derived. The results show that the learning method has the properties of less previous information about objects, better compaction and accuracy for the model. |
